Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the connector size is reduced for mobile devices, then the device size is reduced, but the structural strength and lifespan of the connector deteriorate
Solution Approach 1:
The patent employs metal members (first metal members and second metal members) integrated with the plastic connector bodies. These metal members provide enhanced mechanical strength and durability while allowing the overall connector size to remain compact. The metal members serve as both structural reinforcement and electrical connection elements, resolving the contradiction between miniaturization and strength maintenance.
2Volume of moving object
If the connector size is reduced, then the device size is reduced, but the durability during plugging and unplugging operations deteriorates
Solution Approach 1:
The integration of metal members with the plastic connector body creates a composite structure that combines the flexibility and ease of molding of plastic with the strength and durability of metal. This composite construction enables the connector to withstand repeated plugging and unplugging operations without structural damage or terminal elasticity loss.
Solution Approach 2:
The connector is divided into distinct functional components: the plastic body providing insulation and basic structure, and the metal members providing strength and electrical connection. This segmentation allows each material to perform its optimal function, with metal members specifically handling mechanical stress during mating operations.
3Device complexity
If traditional connector structures are used, then the structure is simple, but the current transmission capacity is limited
Solution Approach 1:
The metal members serve multiple functions simultaneously: they provide structural reinforcement to the connector body, act as electrical connection terminals for current transmission, and enable both signal and power pathways. This multi-functionality increases current transmission capacity without proportionally increasing structural complexity.
